Default Connection armoured calbe to twin and earth cable

mused:

You should run an extra earth wire outside the cable and connect that to the
box also.

No you shouldn't. If the cable were below ground then you'd have to
run the earth in something to mechanically protect it, which negates
the need for the SWA as you may as well run it all in that then.

If you want to run a seperate earth the preferred method is to use a 3
core armoured for single phase supplies.
